Silicon Carbide Refractory Brick For Ceramics Industry

1. Product Overview

This refractory brick is manufactured via precision processes: high-purity silicon carbide crushing, gradient batching, high-pressure molding (to ensure density), and high-temperature sintering (1600-1700℃). The high SiO₂ matrix forms a stable cristobalite structure, which enhances its acid resistance and high-temperature strength-solving the pain points of ceramic kiln linings cracking from thermal shock or eroding from high-temperature gas. Unlike ordinary refractory bricks, it has low apparent porosity (≤25%) and high cold crushing strength (≥80MPa), ensuring long-term stability in ceramic firing environments. Standard shape is brick, with full customization support for non-standard kiln structures.

2. Key Features

Superior High-Temp Performance: Refractoriness 1790℃, load softening temperature ≥1620℃, maintaining structural integrity in long-term ceramic kiln operations (e.g., tunnel kiln high-temperature zones).

Excellent Thermal Shock Resistance: Withstands rapid cooling/heating cycles without cracking, adapting to frequent startup/shutdown of ceramic kilns and reducing maintenance frequency.

Low Impurity & Acid Resistance: Fe₂O₃ ≤1.6% (avoids contaminating ceramic products), SiO₂ ≥93% resists weakly acidic flue gas erosion-ideal for ceramic glaze firing kilns.

High Mechanical Strength: Cold crushing strength ≥80MPa, withstanding the weight of kiln furniture and ceramic workpieces without deformation or breakage.

Cost-Effective & High Capacity: Factory-direct pricing ($450-$530/ton) reduces procurement costs; 30,000 tons monthly capacity ensures timely supply for large ceramic production lines.

4. Application Scenarios

Ceramics Industry: Ceramic tunnel kiln high-temperature section linings, roller kiln roller sleeves, and glaze firing kiln walls-resisting high heat and ensuring uniform ceramic firing.

Metallurgy Industry: Coke oven top linings, hot blast stove regenerator grids-withstanding high-temperature coke gas erosion and hot air impact.

Waste Treatment Industry: Refuse incinerator linings (as carbonized silica brick variant)-resisting high-temperature combustion gas and corrosive residues.
